Review on Munchkin Sleep Toddler Queen Mattresses by Matt Williams

I have only used this on a double bed with mattress and slatted system with stairs in recessed frame (Barn Ceramic Bed). Yes, the manufacturer says it's not intended for this type of bed, but it worked fine for us. We attached metal bars to the slats for extra security and support (another reviewer mentioned he did this with zip ties) and I feel this adds even more stability to an already good product. It was pretty easy to install, if not "1". Minute Installation" as they claim! It took 2 people about 30 minutes to make 2 roof rails (one on each side). The rails fold up and down easily. I'm TERRIBLE to change the fitted sheet - and the rails change/affect how the sheet and duvet or comforter fit the bed but I think that applies to pretty much any product like this overall this is a great product and the price matches the quality!
